Description Tomas Hoger 2020-04-14 21:05:18 UTC 
A flaw was found in the way the TLS implementation in the JSSE component of OpenJDK re-used single null TLS sessions for new TLS connections.  A remote attacker could possibly use this flaw to impact availability of a Java application providing TLS server.
